Background: This study investigated the factors affecting the acceptability in France of abortions. Method: 80 study participants from Toulouse and 124 from Metz judged the acceptability of abortion in 64 vignettes composed of five factors: 1) the adolescent's age (15 or 17.5 years), 2) the adolescent's plans to continue schooling or not, 3) the fetus' age (1, 2, 3, or 4 months), 4) the adolescent's parents' agreement or not, and 5) the agreement or not of baby's father. Results: Three clusters (...) were noted: 1) abortion is never acceptable (8% of participants), 2) abortion is always acceptable (23%), and 3) acceptability of abortion depends on the circumstances (63%). In the majority cluster (3), all five factors had significant effects, but the fetus's age accounted for most of the variance (78%). Conclusion: Most subjects in this study judged, in accordance with French law, that the acceptability of induced abortion in minors depends on the circumstances and, in particular, on the fetus' age.
